so the solution its to grep and replace (take easy, u can made it in geany of venenux) using a regular expresion:

1) open geany
2) load the script
3) menu->search->replace
4) marks use regular expr
5) the word to search will be COMMENT \'.*\'
6) the word to replace it will be empty
7) pull down avanced "Replace all" and select Document
8) that's all

now at least COMMENT keyword was eliminated from script and sqlite can procesed the sql.
